Abstract: Ce jouet (T7) pour animal de compagnie, servant à contenir une ou plusieurs friandises (100) pour animal, présente un corps (92) comprenant une surface extérieure comportant un ou plusieurs évidements (96, 94) destinés à contenir de manière amovible une ou plusieurs friandises (100) pour animal. Ces évidements peuvent présenter une profondeur variable, de façon que l'animal ait plus de difficulté à extraire les friandises placées dans les évidements les plus profonds (96, 94) que celles situées dans des évidements moins profonds. Ces évidements peuvent être circulaires, triangulaires, irréguliers, sous forme d'une gorge, ou peuvent présenter toute autre forme appropriée. La surface extérieure du jouet peut être surélevée pour loger les évidements, ou ceux-ci peuvent s'étendre dans la surface. Ce jouet peut présenter des évidements formant des ouvertures qui s'étendent à travers la paroi latérale du jouet, aux fins de réception de friandises. Grâce à la structure décrite, le propriétaire de l'animal de compagnie peut remplir de friandises les évidements, aussi souvent qu'il le souhaite, afin de maintenir l'intérêt de l'animal pour le jouet. Il est possible d'utiliser diverses friandises possédant des valeurs nutritionnelles et des goûts différents. Etant donné que certaines friandises sont plus difficiles à extraire du jouet que d'autres, l'animal peut être occupé pendant plusieurs heures avant qu'il ne soit nécessaire de remplacer à nouveau les friandises, lesquelles peuvent être maintenues dans les évidements par friction, adhésif ou adhésion.

Title: Http session control
Inventor: FEIT FIL
IPC: G06F11/34
Filed: 1998-12-23
Granted: 2009-01-20
Abstract: A means of providing session control over a network such as the Internet is disclosed. Traditionally, the Internet protocols define a session between a client and a server as one page request and one page response. This does not permit the servers to ascertain how long a client is accessing a page or whether a page containing database information is being viewed by two clients simultaneously. In accordance with the present invention, a page contains a script that causes the page to send beat signals from the client to the server at particular times to indicate to the server that the client is continuing to view the page. When the client releases the page, the beat will stop and the server will know that the client has released the page.

Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.

Title: Electric service load limiter
Inventor: FULLER ALAN D
IPC: H02J3/14
Filed: 2001-03-13
Granted: 2004-11-30
Abstract: An electric service load limiter limits the level of current a consumer receives from an electric utility power line. An electronically controlled power relay switch, connectable between the utility power line and the consumer's electric power circuit, couples electric current to the consumer's power circuit and interrupts the flow of current through the consumer's power circuit when the level of current flow exceeds a predetermined maximum level. A sensor produces a sensor signal which is proportional to the amount of current flowing through the consumer's power circuit and is coupled to a logic circuit. The logic circuit compares the resulting sensor signal to a signal representing the maximum current level of the consumer's electric power circuit, as preselected by the consumer's electric utility company. If the sensor signal reflects a level of current greater than the preselected maximum level, the logic circuit causes the automated power switch to disconnect the consumer's electric power circuit from the utility power line, thereby disrupting electrical service to the consumer. A reset switch circuit is coupled to the power relay switch. The reset switch may be either manually or automatically operated, and causes a reset circuit to produce a single reset signal each time the reset switch is operated. The reset signal causes the automated power switch to couple current from the utility power line to the consumer's electric power circuit and restore electric service to the consumer.

IPC: H04Q3/42
Filed: 2001-11-27
Granted: 2007-01-16
Abstract: Each time the time in a timer is re-set, a control section overwrites a difference integration value corresponding to the amount of the change from a reference value "0" in an registration memory of a memory section. When a call is sent from an extension to an outside line, the control section first reads out the difference integration value from the registration memory and stores on a management table the read-out difference integration value and call beginning time information in association with the call-sending extension. If the call between the extension and the outside line is finished, the control section executes an accounting calculation process for a call charge associated with the call-sending extension, on the basis of call end time information, the difference integration value stored in the registration memory at this time, and the call beginning time information and difference integration value associated with the call-sending extension, which are registered on the management table.
